To retract the foot, hold up the projector while pressing the quick-release button, then

slowly lower the projector. Screw the rear adjuster foot in a reverse direction.

If the screen and the projector are not perpendicular to each other, the projected picture

becomes vertically trapezoidal. To correct this situation, adjust the value of Keystone in the

Picture menu, on the projector control panel, or on the remote control. See "Correcting

keystone" on page 25 for details.

Correcting keystone

Keystoning refers to the situation where the projected picture is noticeably wider at either

To correct this, besides adjusting the height of

the projector, you will need to manually

correct it following ONE of these steps.

•Press / on the projector or

remote control to display the status bar

labelled Keystone, then press to

correct keystoning at the top of the picture

or press to correct keystoning at the

bottom of the picture.

•Press MENU on the projector or MENU on the remote control. Go to the

Pro-Picture > Keystone menu and adjust the values by pressing Left/ Right on the

projector or remote control until you are satisfied with the shape.

For example,

Auto-adjusting the picture

In some cases like with computer timings,

you may need to optimize the picture

quality. To do this, press AUTO on the

projector or remote control. Within 3

seconds, the built-in Intelligent Auto

Adjustment function will re-adjust the

values of Frequency and Clock to provide

the best picture quality.

The current source information will be
